I am interested in this bicycle because it is a comfort bicycle that feels lightweight. The problem is I cant seem to find anywhere online or through treks website on how much it actually weighs. If another comfort bike is lighter with the same features I will go with that, even if it is more expensive. I want to stick with a comfort bike that is as lightweight as possible because I will be hauling it around a lot. I live on the second floor and I have a bad back. If you know of any comfort bikes that provide a good ride and are lightweight let me know. I realize these are heavier then road bikes and such but a comfort/hybrid bike suits my needs for what I will using it for.
